CURB-CON DUIT.

Specification of Letters Patent.

Patented March 6, 1906.

Application filed May 8, 1905- Scrial No. 259,314.

To all whom it minty concern:

Be it known that I, JAMES C. MARRIOTT, a citizen of the United States,residing at New Dorp, in the county of Richmond and State of New York,have invented certain new and useful Improvements in Curb-Conduits; andI do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appcrtains to make and use the same.

My invention relates to curb-conduits and coverlates therefor, and isarticularly applicab e to the snow-removal conduits covered by my PatentNo. 752,911, dated Feb ruary 23, 1904.

My invention consists in the novel construction of the cover-plates, inthe securing of certain of the cover-plates to the conduit, and in otherfeatures of invention hereinafter pointed out.

The object of my invention is to facilitate the uncovering ofcurb-conduits in order to expose the same for the purpose of depositingsnow therein, for the purpose of cleaning said conduits, or for anyother purpose.

I will now roceed to describe my inven tion with re erence to theaccompanyin drawings, and will then point out the nove features inclaims.

In said drawings, Figure 1 shows a crosssection and erspective view of acurb-conduit provided with my improved cover-plate. Fig. 2 shows a sideelevation and partial section of a curb-conduit provided withcoverplates constructed and arranged in accord ance with my invention,the view bein taken from the streetdooking toward the cur b.

Referring now to the drawings, and at first particularly to Fig. 1, 1designates a conduit such as is covered by my said Patent No. 752,911.Such conduit is shown as located at the curb of the street, being formedin a concrete block 2, and beneath said conduit are shown ducts forelectric wiring 3 and a water-main 4 but of course the conduit may haveany preferred construction.

5 is a hydrant adapted for admitting Water from water-main 4 through aconnection 6 to the conduit 1 for the purpose of carryin off snow insaid conduit, as described in my a orementioned patent. Numeral 7designates the aforementioned cover-plates for said conduits. Theseplates are preferably angleplates, seated at their inner edges on ashoulernploy for the same conduit cover-plates o der 8, formed in block2, and seated at their outer edges on a similar shoulder 9, formed insaid block. Said cover-plates are provided with c fpenings 10, adaptedto permit entrance of sur ace-water from the street into the conduit 1.The plates are adapted to be pushed back over the sidewalk for thepurpose of opening the conduit, the interior of the conduit in rear ofthe curb portion of the coverpjlate being entirely clear to permit this.ach cover-plate is provided with an opening 11, adapted to receive abent tool 12, such as is illustrated in the drawings, the bent end ofwhich tool when the latter is introduced into said opening, as shown,will engage the lower surface of the cover-plate, so that said tool maybe used as a lever to tilt the cover-plate upward and then to push itback over the side-walk. In this way the entire interior of the conduitis eX osed.

The upper sur ace of the cover-plate may be roughened or provided with atop layer of concrete, cement, or the like, the same as ordinarymanhole-covers. Ordinarily it is necessary only to open the conduit atintervals, and it is desirable, particularly when the street has a steepgrade, that the cover late shall be prevents rom shifting longitu inallyof the conduit. For these reasons I frequently two or more differentlengths, relatively short plates being located at 1ntervals, and itbeing intended that these plates only shall be ushed back ordinarily.The longer plates eing naturally heavier need be disturbed only at rareintervals, if at all.

he plates which are not to be disturbed ordinarily may be provided withpins or dowels 13, adapted to fit into sockets 14, formed or embedded inthe material of the conduit 1. These pins when fitting into such socketsprevent their cover-plates from shifting longitudinally of the conduit.

It is obvious that my invention is susceptible of many variations andmodifications and that said invention is applicable not only tosnow-removal conduits, but conduits of other t pes. I do not limitmyself, therefore, to tlie particular details of construction andarrangement shown in the drawings.

What I claim is 1. The combination of a curb-conduit and a curb-platecover therefor, said conduit having supports for the free ends of saidcover and having a clear space in rear of the front of said cover topermit rearward movement thereof, said cover having a top portion and afront or curb surface, both resting on the said supports of the conduit,the sides of said 5 cover belng free.

2. The combination of a curb-conduit and a curb-plate cover therefor,said conduit having supports for the free ends of said cover and havinga clear space in rear of the front of said cover to permit rearwardmovement thereof, said cover having a top portion and a front or curbsurface, both resting on the supports of the conduit, said front portionhaving an opening for the entrance of surfacewater, the sides of saidcover being free.

3. The combination of a curb-conduit and a curb-plate cover therefor,said conduit having supports for the free ends of said cover and havinga clear space in rear of the front of said cover to permit rearwardmovement thereof, said cover having a top portion and a front or curbsurface, both resting on the supports of said conduit, and having alsomeans for engagement by a manipulating tool, the sides of said coverbeing free.

2 5 4. The combination of a curb-conduit and a curb plate covertherefor, said conduit formed in proximity to the curb of a street, itsfront being approximately at the streetlevel and its rear beingapproximately at the sidewalk-level, said rear and front ortions havingdepressed shoulders upon wiich the top andfront portions of said coverrest, said cover having a top portion forming substantially a ortion ofthe sidewalk and a front portion orming a curb front, the sides of saidcover being free, and the portion of the conduit in rear of said frontportion of the cover being clear to permit rearward movement of saidcover.

5. The combination of a curb-conduit and a series of curb-plate coverstherefor, said conduit having supports for the free ends of said coversand having a clear space in rear of the fronts of said covers to permitrearward movement thereof, said covers having each a top portion and afront portion forming a curb front, both resting on the said supports ofthe conduit, the adjacent edges of the several covers being disengagedas regards rearward movement of one of said covgrs with respect to theothers and the conuit.

6. The combination of a curb-conduit and a series of curb-plate coverstherefor, said conduit having supports for the free ends of said coversand said covers having each a to portion and a front portion forming acurb front, both resting on the said supports of the conduit, certain ofsaid covers locked to the conduit as regards longitudinal motion withrespect thereto, and certain of said covers being rearwardly movablewith res ect to the other covers and the conduit, t e sides of suchrearwardlymovable covers being disengaged from the other covers and theportions of the conduit in rear of such rearwardly-movable covers beingclear, to permit such rearward movement.

In testimony whereof I affix my signature in the presence of twowitnesses.

JAMES C. MARRIOTT.
